Ryan Air may be one of the most well known budget European airlines out there. They have over 2,000 flights out of 33 countries per day throughout the UK and EU. They have different fare tiers to choose from and their prices are very reasonable. If you need something to get you from point A to point B without the bells and whistles, this is a good dependable airline.
As with any other airline, one needs to be diligent in knowing what each fare tier includes. The absolute cheapest fare will get you a seat (with an option to choose your seat starting at an extra £5) and two pieces of hand luggage (this would include a small bag such as a purse or laptop bag and a small suitcase measuring no bigger than 55cm x 40cm x 20cm that’s 21.5 x 7.8 x 15.7 in inches and weighing no more than 10 Kilograms). They are pretty strict on the small suitcase size, so make sure if you are not paying to check a bag that the size of your luggage is no bigger than their very specific measurements or you may have to pay to check your bag.
